Serial No. 149,036;

This invention relates particularly to what are 'known as. gillrboXes used especially in the worsted industry forstraightenvingwoolfibers and laying them'parallel. y

V Such gill boxesxot. the common: type include'two parallel top screwsfand under these trwoparallel bottom screws,- so arranged in a frame and driven'. in such a manner that what are known asifallers, which'.v are sublo stantially rectangular bars otinetal4 having one or more rows-of: pins'projecting upwardly therefrom, will bel caused to move in -one' direction betweenL the top screwsl passing through the fiber and straightening it i5 out;v untilY each' one'reaches thev end of the top screws, when by means of suitable cams itY isV forced down: .inv engagement vwith bottom screws by which it'. isl carried' back be-A Y neathv the startingpoint, from whence it is lifted again t'obeengagedfby the toplscrews and again carried forward.

Itiis'foundY thatthef'dirt and short 'fibers have a strong tendency to cling to each taller, and in fact wrap around it from the 25, top to the bottom.' As it yis necessary to keep these allers substantially clean, the machine must be stopped from time to time,

usually several times a week, and as the fallers are quite close together each one must be so removed and cleaned causing great loss ot time.V A

, I have discovered that by locating a cleaning brush under the'bottom screws so that it will be in contact Vwith the bottom faces of the fallers, as they'move, not only thebottom but the entire taller will be cleaned.

It appears that the longer of the shorter libers being caught by the brush, wipe around and carry with them the short bers e and the dirt so that all are* caught and removed.

Moreover as the fiber moves faster than the feuer pins, moa of the dust or da which comprises some 90 of the`waste'is Ycaught 5 on what might be called the back side of each taller and if .thisback Vside is constantly kept clean and thebottom is also kept clean as by my device, it does not gum up but* "seems to slip'down and around the bottom, on to the brush where it accumulates on what might be Called the from sie@ from kwhich it drops ol'flj by gravity on tothe ground.l By so keeping the taller body always Cleany instead of removing the allers for'cleaning twice a week as isv customaryl lind if`Y` my fallers are removed every three months and carefully cleaned or polished it iba-sufficient.

the'vusual type, parts beingfbroken; away so' as to make the constructionA clear.Y

.Figi 3 is a s ectionthrough guide screw. 32.

In the drawings, A. is theframe 'of a gill' boX and .Bi ands@ are the top1 screws while D andF are the bottomscrews.

10,10 and 1-12, 1.1; are guides for -thejtallers M','M1, each ot which-has ordinarily` four faces, l .andA 2 being :the back `and front faces,.5 beingfthes top face andv 3f the bottom-face., From the top face -ofeach 'aller f vproject oneor more-rows ot pinsA, 4,

As shown Fig. 2, -tfh'esel allersf M', SM, travel inthe direction of thearrowvalong with the stock G which'passesl between a kfront roller andY an. apron 22', carried by `roller 21 andthen are forced: down by cams of well known. construction, but 'not' shown inv detail, `to,y and. betweenthey bottomv screws F and D,'during which they travel initlie direction of thel bottomL arrow .until ltheyxare vagain raised by otherfc'ams-.between the top screwsv B. and'G. f

rl`he bracket' 46; is vfastened toV the'iframe by a bolt 7 andA-car-ries-at onewendxan open bearing v in which is a pivot 44B for a yoke. 42through which passes thefbrush n .support K which includes a shank 41 adjnstablein yoke by means of ascrew 43,.

and having at one end 49 an adjustable weight 47, whose location is determined by adjusting screw 48.

The other'end is bent at l0 to carry a brush socket 31 held on by means of guide screw 32 and fastened to brush H by screws 33. Screw 32 enters loosely slot 35 in end 40.

This brush H is of such distance from front to back that it spans the space between at least two fallers M as they travel, and is so located that as they travel along the screws, the bottom face of each faller is engaged and cleaned.

By using an open bearing the whole j brush and its support can instantly be re` moved for cleaning, other purpose.

I prefer to make slot 35 in end l0 a little longer crosswise and lengthwise than guide screw 32 to allow brush H to press evenly against the whole bottom face of each faller.

I claim: v

l. The combination in a gill box having means to cause the stock to move horizontally in a given direction and having top screws and bottom screws together with fallers each of substantially rectangular cross section and each having pins projecting from its top face and having a flat bottom face, said fallers being caused to move along and between the top screws whereby the pins penetrate the stock and to move in the same direction therewith but at a slower speed and adjusting or for any which fallers then descend and move each in I an upright position in the opposite direction tion therewith but at a slower speed and which fallers then descend and move each in an uprightposition in the opposite direction between the bottom screws; of a flat faced brush positioned under the bottom screws of such size as to span the space between two fallers with the bottom faces of which it engages while said fallers are supported by said bottom screws; and means to yieldingly hold said brush in contact with the bottom faces of said fallers as they move along the bottom screws.

3. The combination in a gill box having means to cause the stock to move horizontally in a given direction and having top screws and bottom screws together with fallers each of substantially rectangular cross section and each having pins projecting from its top face rand having a dat bottom face, said fallers being caused to move along and between the top screws whereby the pins penetrate the stock and to move in the same direction therewith but at a slower speed and which fallers then descend and move each in an upright position in the opposite direction between the bottom screws; of a-flat faced brush positioned under the bottom screws at a position nearer the lifting than the receiving end thereof, said brush being of such size as to span the space between two fallers with the bottom faces of which it engages while said fallers are supported by said bottom screws; and means to yieldingly hold said brush in contact with the bottom faces of said fallers as they move along the bottom screws.

are supported by said bottom screws; a brush Y socket medially fastened to the bottom of said brush and having a cylindrical hole and a guide screw which enters said hole; a bracket xed to the frame of the gill box having at the top an open bearing; a yoke having a pivot w i ing; a brush support which passes adjustably through said yoke and which at one end enters the socket hole and has a transverse slot into which said guide screw enters and at the other end has an adjustable weight whereby the brush is held yieldingly in contact with the bottom faces of said fallers as they move along the bottom screws.
